Well, I am currently reading, called "Living Simply With Children". A lot of things they suggest, we already do in our family. Family nights, game nights, movie nights, eating dinner together, making time for each other and many more are talked about in this book.
I highly suggest that if you are looking for some great ideas (and resources - suggested throughout the book) then you pick this one up. I know our local library has one but after reading only a couple of chapters I knew that I wanted to have this one to refer to in my home library (nothing grand, just a bookshelf or six throughout the house!).
Check out a sample of the book here.
What can you do to simplify your life today?
